GEORGE F. (JONNER, OF PORT HURON, MICHIGAN.

CONVEYER-CHUTE.

srEoIFIcArIoNfQrmin part of' Letters meet to. 761,761, dated Jun; 7, 1904.

Applicationfiled March 20, 1903- To all whom it may concern: Be it known that I, GEORGE F. CONN-ER, a citizen of the United States of America, and a resident of the city of Port Huron, county of St. Clair, and State of Michigan, have invented certain new and useful Improvements in Con veyer-Ohutes, of-which the-following is a full, clear, and exact specification.

This invention relates to improvements in conveyor-chutes, and especially to that class comprising telescoping or extension chutes adapted for blowers. I 1 1 The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appendedclaims.

As hereinafter illustrated and described, a form of conveyer is shown which is-especially adapted for use as a straw-stacker for threshing-machines or the like, although obviously it may be adapted to other uses.

Referring to the drawings, Figure 1 is a View, partly in elevation and partly in section, of'a conveyer-chute which embodies theprincipal features of the invention. Fig. 2 is a view in cross-section through the chute on line 2 2 of Fig. 1. Fig. 3 is a view in cross-section on line 33 of Fig. 1. Fig. i is a fragmentary view showing the outer end of the main trunk. Fig.5 is a view, partly in elevation and partly in section, of a modified form of chute. Fig. 6 is a view in cross-section on line 6 .6 of Fig. 5. a Fig. 7 is a frag-v mentary view of the outer end of the chute illustrated in Fig. 6. Fig. 8 is avi ew of an outer sheave and portion of the runway. Fig. 9 is a fragmentary view of a friction-roll. Fig. 10 is a detail View showing method of attaching the flexible connections.

Referring to the drawings, A represents the main section or trunk of a conveyer, which is movably secured by connecting sections A A to a base B. The means of connection between the base and trunk may be of any form or design. Preferably they should be adapted to allow adjustment of the trunk in both horizontal and vertical planes and do not form an essential part of this invention. As herein indicated, the base B is adapted to be secured to the frame of a separator or like 5 machine. Said trunk A is preferably cylin- SerialNo.14=8,662. {N0 model.)

drical in cross-section, althoughit may be elliptical or the like.

A telescoping section O, hereinafter d6Si,Q'

nated the extension, has longitudinal sliding engagement with the trunk A. The outer end 0 of said extension may, if desired, carry a deflector, as the hood D. The inner diameter of said-extensionO approximates the outer diameter of the trunk A and its periphery conforms to the shapeof-the trunk. The two parts are held in any required position by the following mechanism: Sheaves E are rotatively secured to the outer end of the chute A at diametrically opposite points. In a preferred method of construction a collar (0 is provided, preferably of cast or malleable iron or the like, of sufficient stiffness to retain its shape under lateral pressure. The sheaves are mounted in said collar at opposite extremities of its vertical diameter. so as to revolve in a vertical plane. A pocket at or sheave-hole for each of said sheaves is provided in said collar,

, each pocket a projecting slightly into the interior of the chute, the metal of the trun' k being bentto form ac'lose jointaround it. The extension in the preferred construction comprises two. curved sheet-iron plates united throughout-their length by channel-ironsc which are provided with lateral flanges, to Y inI'a-suitable manner, aflords one convenient means of mounting the drums.- Said drums are rotated together by any connecting mechanism which will insure unison of movement. Preferably this comprises sprockets H and chain H, the drums being manually rotated by a crank H secured to one of the drumjournals. Flexible connections J of wire, steel, hemp rope, or the like, are each secured by either end to the inner end of the extension at the opposite extremities of its vertical diameter, so as to be in alinement with the drums and sheaves. Said flexible members are each given a few turns around the respective drums and passed through the corresponding sheaves at the outer end of the trunk, clearance being afforded for the ropes in the preferred construction by the channel-iron of the extension through which they are passed. It will be understood that the upper and lower connections are so made as to work in unison, one of the ropes being crossed to impart the desired motion. 7

In order to take up any slack in the rope or cable, one of the ends may be secured to an eyebolt K. which has screw-threaded engagement in lugs L L, secured by suitable means to the end of the extension, check-nuts k securing the eyebolts from accidental displacement.

A rider or friction-roll M maybe journaled on the upper lug L to have rolling contact with the flexible connections which pass beneath it or with the trunk. The other lug L may carry a friction-roll N, which is adapted tobear against the trunk, and thereby facilitate the sliding of the two parts on each other. The roll is especially advantageous when the extension is at the outer end of its throw.

The binding and cramping which are prevalent in the form of conveyer-chutes now in use, so far as known to me, are eliminated to a large degree by the double rope connections acting at opposite points of the periphery of the extension, the unison movement of the two giving an even pull upon the extension at its lower end, so that it does not tend to stick. In case the angle of elevation of the trunk is very slight or the extension is nearly at its outer limit of motion the weight of the unsupported end tends to cause the extension to bind the trunk against the upper side of and at the lower inner end of the extension. The two ropes apply the power directly in line with these points of greatest resistance, and therefore readily move the extension, while the roller action of the upper sheave and the lower rider insures ease of operation. The channel-irons which embrace the sheaves tend to prevent any lateral shifting or twisting of the parts upon each other, so that the hood may be readily deflected without causing sticking of the telescoping surface.

The extension may be made with its perpendicular diameter long enough to allow the ropes to pass between the extension and the trunk without the use of the channel-irons, although the latter are preferable. In such construction the outer sheaves may be turned to rotate in planes parallel to the horizontal diameter of the extension. They may be mounted directly on the sheet-metal end of the extension, which is indented to form retaining-pockets, but the rigidity afforded by the collar of the improved construction makes it preferable.

The flexible connection may comprise a single rope attached as shown, but passing around both drums and having the proper lead through guide-sheaves, so as to he attached at the opposite points of the extension. The connecting mechanism of the drums may be omitted in such instance.

The two rope connections at opposite points of the extension support the latter when the trunk is elevated appreciably, so that it hangs as though in a rope-stirrup, and therefore does not cramp or bind.

Obviously many details of construction may be varied without departing from the spirit of the invention, and I do not limit myself to any particular form or arrangement of parts except as set forth in the appended claims.
